We recently reported the frequent detection of polyomaviruses (BK virus [BKV] or simian virus 40 [SV40]) in 46% of stool samples from hospitalized children. In order to determine if adults exhibit fecal shedding of polyomavirus, single stool specimens from healthy adults were evaluated by PCR. Overall, 20 (18.2%) of 110 specimens were positive for human polyomaviruses: 9 with BKV, 9 with JC virus (JCV), 1 with SV40, and 1 with both JCV and SV40. Among the 94 subjects without immune compromise, 17 (18.1%) were excreting polyomaviruses. This shedding frequency in adults was significantly lower than that observed in children (P < 0.001). These findings support the hypothesis that the gastrointestinal tract may be a site of polyomavirus persistence, and they suggest a fecal-oral route of viral transmission.
我们最近报告称,在住院儿童46%的粪便样本中频繁检测到多瘤病毒(BK病毒[BKV]或猴病毒40[SV40])。为了确定成人是否存在多瘤病毒的粪便排泄情况,我们通过聚合酶链反应(PCR)对健康成人的单个粪便标本进行了评估。总体而言,110份标本中有20份(18.2%)人多瘤病毒呈阳性:9份为BKV阳性,9份为JC病毒(JCV)阳性,1份为SV40阳性,1份JCV和SV40均为阳性。在94名无免疫功能低下的受试者中,17名(18.1%)正在排泄多瘤病毒。成人的这种排泄频率显著低于儿童(P<0.001)。这些发现支持了胃肠道可能是多瘤病毒持续存在部位的假说,并提示了病毒的粪-口传播途径。
